Candor's Innovative Process Using Organic Liquid Photoresist

Candor Industries is the only PCB company in the world to have perfected a liquid photoresist process. Our primary imaging is a wet process and is not subject to adhesion failures and other defects associated with handling dry films, including foreign objects, resulting in greater line controls at etching.

By using the positive acting photoresist, Candor and thereby the customer does not need to worry about many problems related to conventional manufacturing process. The coating lasts for a very long time and allows us for large stock of material coated already. This allows for fast production, saving time/money for the customer!

The reliability of the resist coating is also superior, as it is scratch resistant. Photoresist coating is consistently 5 microns thick, this is very thin, allowing for better and consistent imaging of layers with 2 mil line and sub 2 mil possible without extravagant costs.

The nature of the resist allows us to keep cupric chloride etching an option for both inner and outer layers, this process gives a better etch than the standard ammonia based etching.
The photoresist was a process found by our President Yogen Patel and was the missing link for his simplified process vision. Over the years Candor has perfected the liquid photoresist based imaging when others have failed, we are the industry experts of liquid photoresist processing.
